esses recognized by us as correct, that the severest judgments of
the authors as to the low psychic activity of dreaming seem to us well
founded.

Perhaps only through still further advance can enlightenment and
improvement be brought about. I shall pick out one of the constellations
leading to the formation of dreams.

We have learned that the dream replaces a number of thoughts derived
from daily life which are perfectly formed logically. We cannot
therefore doubt that these thoughts originate from our normal mental
life. All the qualities which we esteem in our mental operations, and
which distinguish these as complicated activities of a high order, we
find repeated in the dream thoughts. There is, however, no need of
assuming that this mental work is performed during sleep, as this would
materially impair the conception of the psychic state of sleep we have
hitherto adhered to. These thoughts may just as well have originated
from the day, and, unnoticed by our consciousness from their inception,
they may have continued to develop until they stood complete at the
onset of sleep. If we are to conclude anything from this state of
affairs, it will at most prove _that the most complex mental operations
are possible without the cooeperation of consciousness_, which we have
already learned independently from every psychoanalysis of persons
suffering from hysteria or obsessions. These dream thoughts are in
themselves surely not incapable of consciousness; if they have not
become conscious to us during the day, this may have various reasons.
The state of becoming conscious depends on the exercise of a certain
psychic function, viz. attention, which seems to be extended only in a
definite quantity, and which may have been withdrawn from the stream of
thought in Question by other aims. Another way in which such mental
streams are kept from consciousness is the following:--Our conscious
reflection teaches us that when exercising attention we pursue a
definite course. But if that course leads us to an idea which does not
hold its own with the critic, we discontinue and cease to apply our
attention. Now, apparently, the stream of thought thus started and
abandoned may spin on without regaining attention unless it reaches a
spot of especially marked intensity which forces the return of
attention. An initial rejection, perhaps consciously brought about by
the judgment on the ground of incorrectness or unfitness for the actual
pur
